keymap_ui: Ensure keymap UI opens in local workspace (#34291)

Closes #ISSUE

Use `workspace.with_local_workspace` to ensure the keymap UI is opened
in a local workspace, even in remote. This was tested by removing the
feature flag handling code, as with the feature flag logic the action
does not appear which is likely a bug.
